Overview

ISO 7175-2:2019 - Furniture - Children's cots and folding cots for domestic use - Part 2: Test methods specifies the laboratory test methods used to assess the safety and mechanical performance of children’s cots and folding cots with an internal length between 900 mm and 1 400 mm. It is the third edition (2019) and has been aligned with EN 716-2:2017. The document defines test conditions, required test apparatus, procedures and reporting rules so that results are repeatable and comparable.

Key topics and technical requirements

• Scope and general test conditions: Tests are carried out on fully assembled units under indoor ambient conditions (record extremes if outside 15 °C–25 °C). Fabrics intended to be removable are washed per manufacturer’s instructions before testing.
• Test sequence and tolerances: Tests are performed in the order given and on the same cot. Typical tolerances include forces ±5%, dimensions ±1 mm, positioning ±5 mm and specified durations for static and durability loads.
• Test apparatus: Detailed equipment specifications include measuring probes (multiple diameters and shapes), a 10 kg bottom impactor, a 2 kg side impactor with rubber face, a 60 mm polyurethane test mattress, a 100 mm loading pad and a ball-chain test mass for entanglement/snag assessment.
• Test procedures (Clause 6): Comprehensive tests cover
  • Assembly and inspection
  • Stability tests and prevention of unwanted movement
  • Foothold detection and testing
  • Measurement of holes, gaps and openings (inside and outside the cot)
  • Small parts assessment (torque and tension tests)
  • Bite test for coated/soft surfaces
  • Mattress base and cot base folding and impact strength
  • Strength tests for sides, slats, corners, mesh/flexible panels
  • Frame and fastenings: vertical static load, durability cycles
  • Snag points and locking mechanism durability/strength
• Reporting: Requirements for documenting deviations, environmental conditions, and all test results are specified.

Applications - who uses ISO 7175-2:2019

• Manufacturers and product designers - to validate cot designs and ensure compliance with safety test methods.
• Independent test laboratories and conformity assessors - to perform repeatable evaluations and generate test reports for certification.
• Regulators and retailers - to reference standardized test procedures when evaluating product safety claims and recall investigations.
• R&D teams - to benchmark materials, fastenings and mattress bases against recognized impact, durability and small‑parts criteria.

Related standards

• ISO 7175 series (other parts covering requirements and related topics) - see ISO website for full list.
• EN 716-2:2017 - alignment noted in this edition.
• Referenced standards for test materials and instrumentation: ISO 48‑5 (rubber hardness IRHD) and ISO 2439 (foam indentation hardness).

Keywords: ISO 7175-2:2019, children's cots test methods, folding cots safety, cot impact test, cot durability testing, small parts torque test.

through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

4 General test conditions
4.1 Preliminary preparation
The tests are designed to be applied to a cot that is fully assembled and ready for use.
The test unit shall be stored in indoor ambient conditions for at least one week immediately prior to
testing. Any deviation from this procedure shall be stated in the test report.
Before testing, any fabrics intended to be removable shall be cleaned or washed twice in accordance
with the manufacturer's instructions. If no instructions are supplied, the washing/cleaning shall be
described in the test report.
The tests shall be carried out under indoor ambient conditions but if, during a test, the atmospheric
temperature is outside the range 15 °C to 25 °C, the maximum and/or minimum temperature shall be
recorded in the test report.
The cot shall be tested as delivered. If the cot is a knock-down type, it shall be assembled according
to the manufacturer's instructions supplied with the cot. If the cot can be assembled, combined or
adjusted in different ways, the most adverse combination shall be used for each test.
Knock-down fittings shall be tightened before testing. Further re-tightening shall not take place unless
specifically required by the manufacturer.
In the case of designs not catered for in the test procedures, the tests shall be carried out as far as
possible as described, and a list of the deviations from the test procedures shall be made.
4.2 Test equipment
Unless otherwise specified, test forces may be applied by any suitable device, because results are
dependent only upon correctly applied forces and loads, and not upon the apparatus.
The equipment shall not inhibit the deformation of the cot during testing. It shall be able to move in
order to follow the deformation of the cot during testing, so that the loads are always applied at the
specified point and in the specified direction.
All loading pads shall be capable of pivoting in relation to the direction of the applied force. The pivot
point shall be as close as practically possible to the load surface.
4.3 Application of forces
The forces in the static load tests shall be applied slowly enough to ensure that negligible dynamic force
is applied.
The forces in durability tests shall be applied at a rate such that excessive heating does not occur.
4.4 Tolerances
Unless otherwise stated, the following tolerances apply:
—  Forces: ±5 % of the nominal force;
—  Masses: ±0,5 % of the nominal mass;
—  Dimensions: nominal dimension ±1,0 mm;
—  Angles: nominal angle ±2°;
—  Positioning of loading pads: ±5 mm;
—  Duration of forces: (2 ± 1) s for durability tests;
(10 ± 2) s for static load tests, including tension, torque and bite
tests.
The tests are described in terms of the application of forces. Masses can, however, be used. The
relationship 10 N = 1 kg shall be used for this purpose.
4.5 Test sequence
The tests shall be carried out in the order laid down in this document and on the same cot.
4.6 Prevention of movement during test
If the cot tends to slide or roll during the tests specified in Clause 6, it shall be restrained by stops (5.6).
